Microsoft Teams Add-in Automatically Disabled in Outlook

by

Many users experience an issue where the Microsoft Teams Meeting Add-in for Outlook becomes disabled. This prevents them from scheduling Teams meetings directly from Outlook, causing frustration and workflow interruptions.

This problem usually happens when Outlook detects performance issues and places the Teams add-in under Disabled or Slow COM Add-ins. Fortunately, you can re-enable it easily using the steps below.

Method 1: Enable Teams Add-in from Slow and Disabled COM Add-ins

  1. Open Outlook.
  2. Go to File.
  3. Look for the yellow highlighted “Slow and Disabled COM Add-ins” option and click it.
  4. Locate Microsoft Teams Meeting Add-In for Microsoft Office.
  5. Select Always enable this add-in → click Apply.
  6. Restart Outlook.

Method 2: Enable Teams Add-in from Outlook Options

  1. In Outlook, go to File > Options > Add-ins.
  2. Scroll to the bottom — the Teams add-in will likely show under Disabled Add-ins.
  3. At the bottom next to Manage, change the drop-down to Disabled Items and click Go.
  4. Select the Microsoft Teams Meeting Add-in → click Enable.
  5. Restart Outlook.

Why Does This Happen?

  • Outlook automatically disables add-ins that may impact performance.
  • The Teams add-in sometimes gets flagged even if it’s working correctly.
  • Ensuring it’s always enabled resolves the issue for most users.

Final Thoughts

If the Teams add-in keeps getting disabled, you may also want to:

  • Update both Microsoft Teams and Outlook to the latest versions.
  • Repair your Office installation via Control Panel > Programs > Office > Repair.
  • Check with your IT administrator if group policies are restricting the add-in.

✅ With these steps, you should be able to get the Teams add-in re-enabled in Outlook and start scheduling your meetings seamlessly again.
